We’ve developed a simple yet effective application to help you save battery power on your Android devices.

We want to make your phone's battery last longer, so we've developed this app, which allows you to set a black background image as your live wallpaper.

We've set a black background to make your phone's power consumption more efficient.

Our application is compatible with most mobile phones and tablets, and it supports screen switching.

We hope you will enjoy our application.

We will try our best to make the app better and better, so if you have any suggestions or comments, please let us know.
